WILLIAM G. N ORRIS, OF SEATTLE, WASHINGTON.

SAFE 0R VAULT.

To all whom it may concern:

Be it known that I, WILLIAM G. NoRRIs, a citizen of the United States ofAmerica, and a resident of the city of Seattle, in the county of Kingand State of Washington, have invented certain new and usefulImprovements in Safes or Vaults, of which the following is aspecification.

This invention relates to safes or vaults, and has particular referenceto that class thereof known as burglar proof 7 safes.

The primary object of my invention is the provision of an improvedstructure whereby superior protection to the mechanism for locking thesafe door is afforded.

With the above, and other desirable objects referred to hereinafter, inview, the invention resides in the construction combination, andarrangement of parts as set forth in the following description anddefined in the appended claim.

With reference to the accompanying drawing, wherein like referencenumerals designate corresponding parts throughout: Figure l is a planview in partial section of a safe embodying the features of my invention. Fig. 2 is a view in front elevation of such a safe shown inpartial broken section, and Fig. 3 is a fragmentary sectional view onlarge scale, taken on line 3-3 of Fig. 2.

In the drawing reference numeral l designates a safe body provided inits front wall with a door opening about which extends the door jamb, as2. The said body and jamb, in practice, constituting an integralstructure formed of unmachineable metal, such, for example, as manganesesteel.

Fitting in the jamb 2 is a door 3,which, as shown, is of rotary type andprovided with the usual lugs, as 4c rfor engagement with similar lugs as5, of the jamb. The door 3 is supported on a crane hinge 6 in the usualmanner, and the ordinary rack and pinion provided to rotate the door inits seat.

In the solid body portion or jamb 2 I provide, at a suitable point, achamber 7 adapted to receive a lock casing as 8. This chamber ispreferably provided with a wall of machineable metal convenientlyconsisting of a soft metal or steel insert 9 located in position duringthe casing of the safe body.

Specication of Letters Patent.

Application filed April 8, 1908.

Serial No. 425,929.

lhile I have shown (see Fig. 3) the chamber 7 and casing 8 with curvedupper and lower wall surfaces which are substantially semicircular incross section they may be of a different form. I prefer, however, tocurve the top and bottom surfaces of the wall and casing so that thesame may be readily ground or finished to obtain a spaceless,metal-to-metal contact between the lockcasing and wall of the chamber.

Mounted in casing 8 is a lock bolt 9 which is adapted for engagementwith the door 3 to lock the same from rotation after the door has beenproperly seated in its jamb. This lock bolt is connected in any wellknown manner for operation by a rotatable spindle or arbor 10 fittingrotatably in an aperture as 11, provided in the body portion or jamb 2during the casting thereof and subsequently ground to offer a smoothbearing for the spindle.

The aperture or bearing 11 is preferably formed cylindrical incontradistinction to the well known tapering form common in safe doors,and I preferably abut the inner end of spindle 10 against the wall ofchamber 7. It is therefore apparent that should a blow be deliveredagainst the spindle tending to drive it inwardly the impact would beabsorbed by the body of the safe without obtaining a Wedging effect,such for example, as would result from a blow delivered to a taperingspindle. Furthermore, after the spindle bearing is once lubricated theoil will have less chance to work out' and permit the spindle to bind inthe bearing.

As the body portion or jamb 2 constitutes an integral structure ofcomparatively large bulk it will be obvious that it oers superiorresisting qualities against burglarious attack and therefore affordssuperior protection to the lock.

Having thus described my invention, what I claim as new, and desire tosecure by Letters .Patent of the United States of America, 1s:

A safe or vault comprising a body and a door, said body having about itsdoor opening an integral, cast body portion or amb of unmachineablemetal having a recessed insert of soft metal located in its jamb surfaceduring the casting of such jamb, and an Signed at Seattle, Washingtonthis 31st aperture extending from said recess to the day of March 1908.exterior of said jamb, a lock casing supported in the recess of saidinsert, and an WILLIAM G NORRIS' operating spindle extending throughsaid Witnesses:

aperture and said lock casing and abutting ARLITA ADAMS,

said insert. EDWARD W. CRESSMAN.
